Recently, key equipment for “Guohe No.1” (CAP-1400)，a demonstration project independently developed by China，has been basically completed, and equipment import substituting rate has reached more than 85%, effectively forming the equipment industry chain of 3rd-Generation nuclear power.
As the two major technical routes of nuclear power in China, Both Hualong No.1 and AP-1000/CAP-1400 have already achieved domestication in many aspects, and the percentage of homemade parts has been quite high.
“Guohe No.1” (CAP-1400) was officially announced at the Innovation Conference of State Power Investment Corporation by Qian Zhimin, chairman of SPIC. This technology is based on the introduction of digestion and absorption of AP-1000 technology, through the re-innovation of a large-scale advanced non-dynamic pressure water reactor nuclear power model with independent intellectual property rights, power, up to 1500 MW.
SPIC experts also said that “Guohe No. 1” pressure vessel, steam generator, control rod drive mechanism, blasting valve and other main equipment have all been homemade. In addition, it also announced that it has completed the main design work in the concept design for the F-class 300 MW heavy-duty gas turbine, and now is conducting trial production and testing of key components such as compressors, combustion chambers and turbines.
According to the industry insiders, the first phase plans to build two CAP-1400 pressurized water reactor units. Each unit has a power generation of 1.534 million kilowatts and a design life of 60 years.
